Investigate a complex blood-culture contamination pattern using organism identity, number of positive bottles/sets, and time-to-positivity cues to guide professional reporting
Open case →Select a Learning Case
Troubleshoot and confirm an unexpected carbapenem-resistant phenotype using accepted confirmation principles under a single validated guideline system
Open case →Interpret an invalid molecular run caused by internal-control failure or inhibition and decide on recollection or re-extraction actions
Open case →Judge whether Aspergillus recovery from a respiratory specimen is more consistent with colonization/contamination versus findings that support clinically important isolation, using specimen type and repeatability cues
Open case →Integrate critical CSF microscopy findings with urgent communication and subsequent culture/ID actions under limited guidance
Open case →Interpret an integrated mixed aerobic and anaerobic culture report as a coherent polymicrobial infection pattern rather than dismissing all mixed growth as contamination
Open case →Respond to failed or low-confidence automated identification by selecting confirmatory methods (repeat, MALDI, biochemicals, or reference pathway) before releasing results
Open case →Investigate discordance between viral serology and molecular results using timing, window periods, and assay limitations to reach a cautious laboratory conclusion
Open case →Apply professional biosafety judgment when mold growth appears on culture media, including sealed-plate handling and appropriate workup location
Open case →Differentiate common stool artifacts (yeast, pollen, vegetable cells) from true parasite morphology under limited guidance
Open case →Recognize an intrinsic resistance pattern (e.g., Enterococcus and cephalosporins, or similar textbook intrinsic pattern) and prevent release of misleading susceptible categories
Open case →Troubleshoot a cryptococcal antigen result that conflicts with microscopy/culture or shows titer/prozone concerns using laboratory verification steps
Open case →Decide on rejection or limited examination when stool parasitology specimens are collected in the wrong preservative or arrive after unacceptable delay
Open case →Differentiate Babesia from Plasmodium on blood films using morphologic criteria under limited guidance, recognizing when reference review is needed
Open case →Interpret discordance between a positive gastrointestinal multiplex NAAT and negative conventional culture using method limitations and reporting caution
